Be it known that I, GEORGE L. RoLLrNs, a

' citizen of the United States .residing at duction'of lnovelapparatus for cementing shows an and distributor detached-,and enlar ed. ig. y 4 shows the auxiliary oft-{rear 4distri uter de-` tached and enlarged; Figif is a section stock in the manufacture of boots and shoes and other 'articles wherein it is desired to cause one part te adhere to another part by the use ofrcement.l

United. States Reissue vPatent No; 12,246, dated Jul 26, 1904, and granted toV me describes cementing apparatus designed more especially for cernentin the channels and channel-flaps of outer so es to ycause the channel-flaps to be retained in position to cover the fastenings employed to unite the outer sole to the welt or inner sole.

In the manufacture of boots and shoes it is common before ap lying the outer sole to coat with cement t e' surface ion which the inner side of the outer sole is laid preparator to secur' the outer sole to the s oe, an generally t e surface so coated with cement varies in material and is com osed of leather and leather chips or o'un cork, and for the best results 1n supp ying the cement that ortion of the brush which contacts withy the eather chi s or cork should be more flexible or softert an the portion that a plies ce.- ment to the leather, such as thewe t and inseam.

It is essential'to cover the surface evenly With cement and to secure this I have combined with the brush upon which 'the cement is de osited a means whereby the cement is ldistri Auted across the brush 1n one and preferably then in the opposite direction, so that the bristles of the brush are uniformly supplied as far as possible with cement.

Figure 1 represents in front elevation, partially broken ,out to save space on the drawing, a cementing apparatus con ainin my present invention in one of the est orms now known to me. Fig'. 2 is a side elevation of the upper part of the apparatus shown in Fig. 1. ig. 3 showsv the combined wi er through the tank and valve showing the wiperV and distributor in elevation. Fi 6 is a perspective view of the brush detached.

The standard A', tank B', valve-carrying lever D,.upon which is mounted the valve D the adjusting device a', the lever D, the ro b, the springE, the rotating shaft e", hav` a pulley ei to receive a belt by which tllge shaft-` maybe rotated, and the bearings for said shaft arefand may be all as provided for in my said atent.

posed of a truncated body -c and a series of ristles c', the bristles at the inner end of the bein preferably shorter or `stiffer than the brist es at the outer or smaller diameter of the body, the construction of the bristles being such that the bristles nearest the outer end of the body of thebrush, which bristles ar to contact with the leather chips or cork in laid u on the middle portionof the inner so e, shallact with less tendens to disturb the material than the bristles at 1e inner end of the body of the brush, which latterbristles act upon the Welt orinseam It will be understood that the lon er the bristle of the brush the more ently t e cement js a plied to the stock of tlgie shoe,' and a lon er ristle is therefore especially desirable fo,` appl ing cement to the chips and ound cork, w ich f are more easily disturberby brushing over the same. By em lo ing stiffer bristles at the inner end of t e rush I find that the quantity of cement applied tofthe Welt and inseam may be so control]edifa" s"tol revent the cement overflowing the edge birilli: welt, and .it will be understood thatthe'firi `ethe charge the cement.

To the front end of thea paratus I have' secured by a bolt 4 the combined-cwi er and distributer F. (Shown detached inf ig. 3.) This device has a slot 5 in anvear f thereof for the reception of the bolt 4. The device f in the' form in which I have herein chosen to illustrate the same is represented as an open These arms are substantially triangu ar in shape, the lower edge being shown as inclined to cross thebrush between the lon if tudinal axis thefeqfgand the ends of. t e `jb'ristles, and theselowfler edges are referably to presentliiangesf f, t eopening b, connecting said lever with the footetreadle The sha t e3 in this present instance of my invention is provided with a brush C, com-y body where the same is of largest diameter r bristles are bent the more freely they will disy IQO box having an end f and two sides f.

` not contact with the box.

between said flanges being V-shaped, wheres, by the bristles of the brush are squeezed to"' gether during the rotation of the brush in sup )lying the cement between the entrance of t e bristles into' the open mouth of the box and the retirement of the bristles from said box.

""lhe box and the flanges so far described are substantially such as illustrated in my said patent with the exception that the ange f* is semicircular for part of its length to enable the body of the brush to run clear of and The flanges described in connection with the wi er-box constitute an important and valua lefeaturc, but are not essential to the invention in all its uses, as appears from the claims herein.

The, box sustains between its sides a distributer g, shown as a rod that crosses the box diagonally with relation to the end f and, as s own, the outer end of the distributer is lower than the inner end thereof, so that cement applied to the bristles of the brush, as fully provided for in said patent, through .opening the valve D will be de osited upon the distributor and will be In e to How lengthwise thereover, so that all of the bristles throughout the entire length of the brush may be supplied with cement and apply the same to the surface over which it rotates. The body of the brush may be of any desired length to apply cement to a surface of whatever width, it being understood that difi1 erent sizes of shoes vary in width from the outeredge of the inner sole to the middle line of the shoe in relation to its len th.

In the resent apparatus t e operator holds the shoe in hand, the welt having been a plied and the chips and cork or whatever iillin is used being also in place, and moves the s oe around, forcing the junction of the upper with the welt against an edge-gage h, (see Fig. 2,) the cement being applied substan ially throughout the shoe from one to its othe end, or starting from the heel at one side thecenient is applied about the shoe toward "its toe end and back aglain to its heel end.

I find in .ractice that t e cement when ap plied to t e bristles of the brush at one point must be worked lengthwise the body of the brush, whatever the length of the body, that all the bristles ma receive cement, and also as there is a consi,` arable quantity of cement on the brush after, has contacted with the surfaces to which the brush should apply cement the cement needs for` the best results to be worked backwardly over the brush, such action securing,f more `unir'orm distribution of the cement and ysavin cement that might be lost orwastedaitthe istribution of the cement over the bristglaifof the brush was in but one direction. l

To secure Aa baekwardtdigutfibuticn of the cement, I employ a distributer that I have designated as an auxiliaryldf distgibutei', and

have shown the same as an inclined finger f connected with-a plate m', provided with a holemi-,tforthe reception of a bolt or sotscrew ma by which to secure said distributer in correct operative relation to the brush. This distributer m receives the cement carried by the bristles of the brush after the bristles have swept over the stock, and the edge of the distributer my next the brush is so shaped and located that the cement travels upwardl and backwardly toward the rear end of t e body of the brush.

I consider it essential for the successful o eration of a cementing-machine of the c ass herein described to employ a distributor upon which cement applied to and carried by the bristles of the brush may be deposited and be carried through said distributer longitudinally with relation to the axis of rotation of the brush to thereby supply all the bristles with cement, and consequently I desire to claim, broadly, a distributer for dis tributing the eementffrom one toward the opposite end of the brush. The essential feature of the distributer, whether it be placed before or behind or elsewhere with respect to the brush or whether one or more be used, is that it shall present an edge in close proximity to and referably slightly within the peripheral su ace of the brush and inclined with respect to the axis of rotation of the brush.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an apparatus of the class described, a rotary brush, a wiper located to act against the sides oi the brush between the axis and the ends of the bristles to wipe the cement toward the ends of the bristles, combined with a distributor presenting an edge in close proximity to the peripheral surface of the )rush and inclined with respect to the axis of rotation of the brush. y

2. In apparatus of the class described, a rotary brush, a wiper located at one side of the longitudinal axis of' the brush, said Wiper acting against the sides of the brush between the axis and ends of the bristles, and a distributor located at the opposite side of the longitudinal axis of the brush, said distributer presenting an edge in close proximity to the peripheral surface of the brush and in'- clined with respect to the axis of rotation of the brush.

3. In apparatus of the class described, a rotar 4brushha Wiper locatemto act against the sides of the brush betwwnlthe axis and the ends ofthe bristles tQ wipe the cement ytoward the ends of the brist'iea distributer located at one side of the longitudinal axis of the brush, said distributor presentin an edge in close proximity to the periphera surface of the brush and inclined with res ect to the axis of rotation of the brush,y an asimilar distributor located at the opposite side of the flanges bein V-shaped, one of saidanges longitudinal axis of the brush, said distribubeing curve upwardly to receive the larger ters acting oppositely in distributing the ,end of the body ofthe brush. cement over the bristles ofthe brush. i In testimony whereof I have signed my 5 4.
